一种基于图和邻接表的站场图模型设计方法

Design Method of Station/Yard Diagram Model Based on Diagram and Adjacency List

在铁路车站的升级改造中,为避免既有联锁数据结构的频繁改动和提高联锁软件的安全性,在既有联锁数据结构的基础上,设计一种用于计算机联锁逻辑运算的站场图模型。该方法采用功能点模型对站场平面布置图建模,并使用邻接表数据结构存储站场信号设备信息及其之间的连接关系,最后举例说明该模型在需求实现中的应用。

In the upgrading and reconstruction of railway stations,in order to avoid frequent changes of the existing interlocking data structure and improve the safety of interlocking software,based on the existing interlocking data structure,a station/yard diagram model for computer interlocking logic operation is designed.This method uses the function point model to model the station/yard layout,and uses the adjacency list data structure to store the station/yard signaling equipment information and the connection relationship among them.Finally,an example is given to illustrate the application of the model in requirement realization.
